P.A. Kelly 1989 Journal Feb. 25 Bionas Reg. Park, Contra Costa Co., California (Sat.) Zoo 107/187 field trip to W end of Bionas Reg. Park (Bear Cr. Ent) to search for amphibians and reptiles w. Harry Greene. About 40 Students - TAs: Scott Edwards, Chuck Yose & ?, Intermittent cloudiness + showers with sunshine. At the Bear Cr. Ent. we noticed 5 Turkey Vultures feeding on what appeared to be a Red Fox carcass or on the N side of the entrance gate. Two hours later (c. 10:15 am) we found a gray fox lying in Homestead Field. It didn't appear injured and although it's eyes were clear and breathing strong we felt it was dying from something (gunshot ?, dog bite ?). I carefully placed it in a student's backpack and drove to Berkeley. It seemed to go into convulsions, scratching at the inside of the pack periodically. Dr. Shirino at (2126 Haste @ Shattuck 808-5041) the Berkeley Dog and Cat Hospital took a look at it and could not detect any reflexes whatsoever. He concluded that it had severe neurological damage poss- ibly due to strychnine poisoning or tetanus. He put it to sleep with an injection of bar- lituate to the heart. I brought the body to the MVZ for an autopsy and specimen.
